Role Description

We are seeking a Nutrition Science Advisor to help advance the science that powers GreenChoice’s Food GreenScore® and dietary attribute system.

As a Nutrition Science Advisor, you will:

• Lead updates to our scoring algorithms (nutrition, processing, safety) based on the latest Dietary Guidelines, peer-reviewed research, and regulatory standards.
• Define new attributes (e.g., “Heart Healthy”) including criteria, thresholds, and citations.
• Evaluate and critique existing scoring systems (e.g., Food Compass, Nutri-Score, Health Star Rating, OptUP) and help articulate GreenChoice’s differentiation.
• Produce concise, implementation-ready documentation (criteria, thresholds, rules, citations) for engineers and customer-facing materials.
• Collaborate with the Science Advisory Board and Lead Data Scientist while also working independently and decisively.

Qualifications

Required:

• Registered Dietitian (RD) in the United States

• 8+ years of experience in nutrition science, nutrition research, food retail, or program development
• Demonstrated ability to translate complex nutrition research into clear rules, criteria, and guidance
• Strong familiarity with nutrition/health scoring systems and labeling programs (e.g., NOVA, Food Compass, Nutri-Score, Guiding Stars, OptUP)
• Excellent communication skills (able to brief retailers, write citations, and present findings concisely)
• Comfort making evidence-based decisions without needing constant data science support
• Mastery of regulatory frameworks (FDA, USDA, AHA, etc.)
   

Preferred:

• Experience designing or refining nutrition or health scoring algorithms
• Experience with startups, innovation programs, or applied research
• Proficiency with data and statistical analysis
